Duru and his friends, who lived in the Village of Numbers, were captured by the Math Demon King.
Every time you answer a question correctly, the bars open, and a friend returns one by one.
This is a math game for preschoolers and elementary school students that even children who cannot yet read can play on their own.
While rescuing thirty friends, you progress one step at a time, progressing from addition to subtraction, multiplication tables, and division.
■ It’s okay if they can't read yet
The questions and instructions are read aloud. Even a six-year-old who doesn't know how to read can start and finish the game on their own without adult help.
The characters speak in distinct voices, so you can tell who is speaking just by listening to the sound.
■ It only gets harder as the child solves
The eighteen levels are divided into six layers, allowing you to progress one step at a time. · Level 1: Adding up to 5 · Adding up to 10 · Adding three
· Level 2: Subtracting up to 10 · Mixing addition and subtraction
· Level 3: Adding with carrying · Subtracting with borrowing · Calculating three numbers
· Level 4: Two-digit addition and subtraction
· Level 5: Multiplication tables (2–5 · 6–9)
· Level 6: Division (Dividing by 2–5 · Dividing by 6–9)
It gets slightly harder if you get it right in a row, and definitely easier if you get it wrong twice in a row.
It does not follow a fixed pace like a workbook. This is because every child has a different pace.
■ Five Boss Battles
A demon appears every time you save six friends.
The Addition Demon, the Subtraction Demon, the Multiplication Demon, the Division Demon, and the Arithmetic Demon King.
Each boss only asks questions based on what has been learned up to that point. It does not confuse the child with questions they have never learned.
You will never lose a boss battle. If you can't deplete your stamina completely, your friends will lend a hand.
For a six-year-old, a defeat screen is simply a reason to quit.
■ The Demon King's Minion Interferes
While you are solving a problem, a minion flies in and swaps the numbers.
If you answer first, you cannot catch them — solving quickly is your defense.
Interference only occurs when you are solving well. It does not further torment a child who is struggling.
■ Thirty Spots in the Friend Encyclopedia
Friends you have rescued take their places in the encyclopedia. Since the spots you haven't rescued yet remain empty,
the child can see at a glance how far they have come today.
Instead of asking, "How many points did you get?", the conversation becomes, "Who did you rescue?"
■ No Competition with Others
There is no leaderboard. The opponent you compete against is your past self.
Like, "You did 655 points better than three days ago!"
Even on days when you don't win, no words are used to belittle the child.
■ Useful for These Situations
· When sitting down to do worksheets always becomes a fight
· When your child cannot read yet and there are no apps available for them to use independently
· When you need to start teaching multiplication tables but do not want to make them memorize them first
· When you want your child to do something that leaves a lasting impression, even if they are just looking at the screen
■ To Parents
· There are no accounts or logins. We do not collect names, photos, or location.
· Game records are saved on the device.
· There are no in-app purchases. There is absolutely no screen where your child could accidentally make a purchase.
· There are ads, but they do not appear while solving problems.
They appear only before a round starts and when exiting the results screen, within a set number of times.
As this is an app for children, we do not use personalized ads.
· You can stop at any time if you need to go to the bathroom. Time is not counted while paused.
· Solving problems is not affected even if the internet connection is interrupted.
This app is a play tool to aid learning and does not replace school education.
Please set the screen time limits yourself.
